A softness : PE-RT relatively soft . No special tools are therefore the construction is relatively low processing costs .
2 , thermal conductivity : for floor heating pipes need to have good thermal conductivity. Good thermal conductivity of PE-RT , the PP-R, PP-B twice the thermal conductivity of the pipe . Very suitable for underfloor heating use .
3 , low thermal shock resistance : PE - RT low-temperature impact resistance is better . Winter construction pipes susceptible to shock and rupture, increasing the flexibility of the construction arrangements.
4 , environmental protection : PE-RT and PP-R can be recycled , do not pollute the environment. The PEX can not be recycled will produce secondary pollution ;
5 , processing performance stability : PEX exist to control the degree of crosslinking and crosslinking uniformity issues , processing and processing of complex pipe directly affect performance . The PE-RT, and PP-R process is simple, consisting essentially of pipe materials to determine performance , more stable performance .
PE-RT can be used to melt connection method , was accidental damage can be repaired using hot melt connection fittings . With warm materials meet product standards creep rupture curves is the only stage without polyethylene crosslinking can be used for a variety of hot water pipes .
Production requirements in accordance with national and international product standards , plastic raw materials to produce hot and cold water pipes and plastic fittings must be determined in accordance with GB/T18252-2000 " plastic piping systems by extrapolation of thermoplastic pipe long-term hydrostatic strength "provides tested and judged by a qualified pipeline Compound. That is, each raw material manufacturers must make to meet the predicted creep rupture strength of the reference curve by curve to warm the pipe product standards, in order to prove the sales of raw materials is qualified. Only do 110 ℃, the thermal stability test under 8760 hours hydrostatic state is unable to prove a point whether pipe materials qualified . If you do not know whether the product is qualified raw materials , it is equivalent to determine the grade of cement did not like the intensity of use can not be determined . Regardless of the variety of pipe laying warm , only used in accordance with product standard requirements for raw materials, and produce reasonable equipment and processes which produce qualified pipe, through proper design , installation and use , in order to reliably ensure radiant floor heating using plastic pipe life of five years.
